docs(CLAUDE): drop stale cuKron-broken gotcha (#999 closed)

[yingjerkao]

Problem

The CLAUDE.md domain-gotchas list claimed:

cuKron GPU compile is currently broken under CUDA 13 (#999) — the CUDA build is not green for that path.

But #999 is closed and cuKron compiles and runs fine under CUDA 13. A "gotcha" that flags a working path as broken actively misleads agents (e.g. it discouraged reusing the GPU Kron path — which #1105 and #1106 both do).

Fix

Remove the stale gotcha bullet.

Verification

build_gpu gpu_test_main (CUDA 13.0, RTX 4070 Ti) builds cleanly and the GPU Kron tests pass — this is the basis for #1105 (Outer via Kron) and #1106 (retire type_promote_gpu_t, which migrates the GPU Kron path). Issue #999 is CLOSED.
